-  This driver can be used to connect to Compaq iPAQ, HP Jornada and Casio EM500
-  PDAs running Windows CE 3.0 or PocketPC 2002 using a USB cable/cradle. It
-  has been tested only on the Compaq H3135, but is rumoured to work on
-  with the H3600 and later models as well as the Jornada 548 and 568.
-  With minor modifications, it may work for other CE based handhelds too.

+  Most devices supported by ActiveSync are supported out of the box.
+  For others, please use module parameters to specify the product and vendor

-  The driver works intermittently with the usb-uhci driver but quite
-  reliably with the uhci driver. However, performance is much better
-  with usb-uhci. It does not seem to work with ohci at all.
-
-  You must setup hotplug to invoke pppd as soon as the iPAQ is connected.
-  A ppp script like the one below should be kept in the file
-  /etc/hotplug/usb/ipaq Remember to chmod +x. Make sure there are no
-  options in /etc/ppp/options or ~/.ppprc which conflict with the ones
-  given below.

-	#!/bin/bash

-	nocrtscts local debug passive $MYIP:$REMOTEIP ms-dns $MYDNS noauth \

-  You must also download and install asyncd from http://synce.sourceforge.net
-  This is required to emulate keep-alive packets which are exchanged by
-  ActiveSync and the iPAQ.
-
-  On connecting the cable, you should see the usual "Device Connected",
-  "User Authenticated" messages flash by on your iPAQ. Once connected,
-  you can use Win CE programs like ftpView, Pocket Outlook from the iPAQ
-  and xcerdisp, synce utilities from the Linux side. Remember to enable IP
-  forwarding. 
+  This driver is only one of a set of components required to utilize
+  the USB connection. Please visit http://synce.sourceforge.net which
+  contains the necessary packages and a simple step-by-step howto.

   If it doesn't work for some reason, load both the usbserial and ipaq module
   with the module parameter "debug" set to 1 and examine the system log.

+  ...if you boot into the bootloader (hold down the power when hitting the
+  reset button, continuing to hold onto the power until the bootloader screen
+  is displayed), then put it in the cradle with the ipaq driver loaded, open
+  a terminal on /dev/ttyUSB0, it gives you a "USB Reflash" terminal, which can
+  be used to flash the ROM, as well as the microP code..  so much for needing

+  NOTE: This has NOT been tested. Use at your own risk.
